Oracle how to replace the OCR/VF disk, many novices are not very clear about this, in order to help you solve this problem, the following editor will explain for you in detail, people with this need can come to learn, I hope you can gain something.

Method 1: disk replacement, disk group unchanged.

Add a disk disk4 disk5 disk6 using a graphical interface or a command line interface

Execute crsctl query css votedisk after adding successfully. The newly added disk information cannot be viewed. The three newly added disks are VF candidate disks and do not have Voting file.

When we delete disk1 disk2 disk3, we write Voting file to disk4 disk5 disk6

Execute crsctl query css votedisk again and you will find information about disk4 disk5 disk6.

At this point, the OCR disk is replaced

Mode 2: disk group replacement

Use ocrconfig-add + OCR2 for OCR replacement by adding mirrored disk groups

After the OCR replacement is complete, you can use the ocrcheck command to discover the OCR1 OCR2.

Then VF replacement, crsctl replace votedisk + OCR2

After the replacement is successful, pay attention to the location of the parameter file of ASM and create a new ASM parameter file in the new OCR disk group (OCR2)

Delete the OCR1 disk group.

Other issues to pay attention to in OCR replacement:

Whether the newly added disk is the same path as the original disk, if it is different, you need to modify the asm_diskstring parameter recorded in the ASM parameter file.
